Im not a fury warrior, but I do know that they are VERY reliant on gear and weapons.. and yours just arent so great right now.. You have solid hit gems, your offhand isnt chanted, your helm is outdated, your shoulders arent chanted, you have a pvp belt and its not even got a buckle, id expect your claimed output with that gear, nothing more
so i just got done with icc and was pulling 5-7k dps. the only things i changed were back enchant and added more hit gems to get closer to soft cap.
do you guys think that was my problem all along?
Don't get caught up in comparing ICC with the 30%buff to doing a ToC without that buff. I'd go to a training dummy and see what your dps is there. I know that it will be non raid buffed but still that's a good place to start.
